Reading early threads can be confusing as so much as changed.

just to clarify... i assume you are talking about lowering my bikes idle to 750 and if that is the case i should also check my auto tune settings are also set this low so it will collect and use the data?
i know how to do both i just want to make sure i have the process correct.
your description of how the bike works (and tuning for) off the line makes a lot of sense.
thanks for taking the time to help us here
Here is what I have used and works well when only getting a minor random decel pop. Take a ride and use the gauges feature of the PV if you dont have a tach on the bike and see what rpm during decel the pop is happening at. example 2500 rpm decel or shift pop go into the spark tables and add 2 degrees timing to the 15 and 20 kpa column in the 2 cells above and 2 cells below and the 2500 rpm cell and then give it a few test rides.
I am running a somewhat aggressive spark table and those two kpa columns go from 17 degrees to 32/37
The premise is you light the fire earlier during decel and there will be nothing left to burn/pop in the hot exhaust system. The next step would be working with decel enleanment tables.
I have a 2007 ECG with a basic Stage 1 K&N filter with Supertrapp SE slip ons. and Jagg Deluxe oil cooler. With the PCIII/stage 1 FuelMoto Map, and the oil cooler the bike ran at 200'F on my McEwan oil temp guage, and ran great. Good gas mileage, nice torque even below 2K rpm and smooth as can be.
My riding style is 200 to 300 mile day trips around New England. Basic touring and looking for good power/good grunt down low, and a cool running engine.
When I went to the PV and supplied FM supplied tune it ran fine, but it also ran about 20' hotter than it did with the prior PCIII.
So now I am just coming up to speed on the more sophisticated features of my PV and trying to make some strategy decisions for moving forward. Given my riding style and habits my main goal is to cool the bike back down as much as possible and hopefully also still have the good power/torque that I currently have with the supplied (Unmodfied) FM tune.
My options seem to be the following, please review and provide recommendations/opinions on where you think I should go.
First option.
Run AutoTune Basic and continue closed loop.
Don't upgrade to Autotune Pro given there would not be that much to be gained given the mild tune of bike and my conservative riding style.
Can I expect running Autotune Basic to have any positive effect on cooling the bike down? (I don't think so, but figure you guys will know.)
Second option.
Import PCIII map and run open loop.
Run AutoTune Basic on the stock ECM to correct VE tables to the bike, then import my previous PCIII map and run open loop.
This would be my attempt at getting bike cooler by leveraging the fact that I have a 07 bike (not TBW) and can import maps. The open loop and the imported PCIII map would allow me to force the AFR to a richer mix, hence cooler running engine and potentially more power. Autotune basic previous to the import would correct the VE tables to my bike as best as I can without the expense of AutoTune Pro.(I admittedly haven't read all 432 pages of the thread and search hasn't given me much to go by.)
Anyone doing this? Can this be considered a string potential solution to my goals?
Third Option
Implement AutoTune Pro (Dish out the dinero and go with AT Pro)
I will most likely do this at some point anyway, but being a old retired guy with lots of hobbies and a fixed income with a mild tune bike and conservative riding style, how much improvement can be had for a rider like me?
Okay, so I'm off to implement Option 1, but look forward to your input on the PCIII import/open loop option AND the Autotune Pro variation.
PS I am not so poor as to not be able to afford AT Pro, so if you think it's a no brainer to go that way, then please say so.
Sorry for my long winded post. I wanted to give you the picture as I understand it. If my thinking is flawed please point ti out.
Ride safe guys!!!

Today i was told by what I would consider a very reputable high performance tuner that when a map is loaded to the ECM of a Harley with the Power Vision, Harleys Digital tech that the dealers use to check and diagnose the stock ECM's cannot see or tell that your ECM has a custom map downloaded from a Power Vision. To put it other way. Power Vision map or tune downloads to the stock ECM are transparent to the Harley Digital Tech diagnostic equipment and even if you don't replace your original OEM map that is downloaded to the Power Vision the first time you marry it to your ECM, the dealer can't tell that you used the Power Vision to flash your ECM and as far as the harley dealer would be concerned your ECM is in stock factory condition.
Is this information accurate?
Thanks
But... Even I am having these site issues. FireFox is double posting but Chrome isn't. For those using FireFox... you may still be lost in the woods for now. Not sure what is going on but the IT guys know about it and are working to see what the issue is.
